We have a weeping cherry tree with a huge root stock branch shooting straight up, starting from below the canopy. We did not realize that it should be cut off and now it's draining the life out of the weeping branches, which barely have any leaves. The tall root stock branch has tons of leaves and even bloomed this year. Can we cut this branch off now or must we wait until fall to prevent "bleed out"? We want to save this tree. Please advise asap.
Hardiness Zone: 5a
